[Discrete Electronics Guy] built a plasma bulb using the casing from an old filament bulb and an ignition coil connected to a high voltage power supply. The power supply is based on the 555 timer IC.

The machine—which has insides made of tungsten and was boosted with a surge of 2 megawatts of power—was able to hold on to the hydrogen plasma at about 50 million °C (122 million °F ...

Reaching durations such as these is a crucial milestone for machines like ... hydrogen plasma for more than twenty minutes through the injection of 2 MW of heating power. Experiments will continue ...

In a global first, Richmond, Canada-headquartered fusion energy company General Fusion achieved the first-ever plasma in a ..
